' This 'invention" relates to an adjustable sash holder, designedto replace the conventional sash weights and spring balances and has for its primary object to "provide a durable and inexpensive device for frictionally retaining the sash in adjusted raised positions.

Anotherpbject of this invention is to provide'a sash retaining device, which will eliminate rattlin of the sash in the frame and which is adjustable for use with various types of sashes, regardless of the weight thereof.

Anotherobject of this invention is to provide means for frictionally retaining a window sash in adjusted raised positions in a window frame, the means including a resilient strip adapted to bear against the edge face of the frame and hold the same in an adjusted raised position, means being provided for adjusting and controlling the pressure of the device against the frame.

These and ancillary objects and other structural features of merit are attained by this invention, a preferred embodiment of which is set forth in the following description and illustrated in the accompanying drawings, wherein:

Figure l is a side elevational view of a sash retaining device or holder, constructed in accordance with the principles of this invention, and showing the same in operative association with a fragmentary portion of a window frame and sash;

Figure 2 is a vertical sectional view of the sash holder, illustrating in section a fragmentary portion of the supporting frame;

Figure 3 is a view in perspective of a fragmentary portion of a Window sash, illustrating the recess formed therein for accommodating the present invention;

Figure 4 is a front elevation view of the instant invention, and

Figure 5 is a transverse sectional View taken on line 5-5 of Figure 2.

Referring now particularly to the drawings, the numeral l0 designates a conventional window sash, which is slidably disposed and mounted in a conventional frame I2, fragmentary portions of the conventional structure being shown by way of environment for the instant invention, generally designated by the character reference I4.

In carrying out the instant invention, a recess [6 is formed transversely in the edge face I! of the sash, adjacent the edge fac of the frame. A resilient elongated strip 48 is anchored at one end, by a screw or similar fastening member 20 to the edge face of the sash, the fastening member being disposed in the edge face. The strip I8 is bent outwardly and downwardly as at 24, to

define an enlarged end 26, which is ofiset'from the longitudinal plane of the anchored end." A cylindrical casing 28 is laterally carried by the terminating portion of the end 26 and is disposed in the recess 16. An opening 30 is formed in the end 26 in alignment with the central portion of the casing 28, for a purpose to be later described. A similar opening 32 is formed in the outer end of the casing and an "externally threaded lugj34 is disposed through the opening 32 'and' longitu dinally disposed inIthe' casing. ,A' disk-shaped. head 35 is formed on the lug and is adaptedto bear against the inner Wall 38 of the recess. compression spring 40 is disposed in the casing. about the lug 34 and bears against the end 26, to urge the offset end 26 and the casing outwardly' from the recess and the edge face I! of the sash..

Means is provided for adjusting the tension.

on the spring 40, to vary the outward pressure on; the offset end 26, bearing against the edge face: of the frame, in accordance with the weight andl type of sash and the amount of clearance be tween the sash and the frame. In the latter respect, a disk 42 is disposed on the externally threaded lug, for longitudinal adjustment thereon, the spring 40 bearing against the disk 42 and the offset end 26. A longitudinally disposed slot 44 is formed in the upper portion of the casing to receive an offset section or lug or tongue 46 on the disk. A transverse adjusting slot or kerf is formed in the outer end of the lug 34 to accommodate a blade or screw driver, which is inserted through the opening 30. Thus, rotation of the lug 34 correspondingly moves the disk 42 longitudinally thereon, the latter being guided by means of the tongue 46 disposed in the slot 44 and movement of the disk adjusts the tension spring.

Thus, it is to be apparent that there has been provided a novel and useful device, which can be secured to a standard window sash, with a minimum of alteration, the only alteration to the frame being the provision of the recess IS. The sash holder Will function in a dependable manner to securely retain the sash in the desired raised position and the frictional pressure thereof can be easily overcome by manual pressure ap plied to the sash to raise or lower the same.

However, since many other purposes and various embodiments of this invention will become apparent to those skilled in the art, it is to be understood that certain changes may be carried out, as coming within the scope of the appended claims.
